The solution to the system of equations using substitution is given by:
x = 4 and y = 2.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the equations are given by:
From the second equation, we have that:
x = -2y.
Replacing in the first equation, we have that:
3(-2y) + 0.5y = 11
-5.5y = 11.
5.5y = -11
y = -11/5.5
y = -2.
Then the solution for x is:
x = -2y = -2(-2) = 4.
The solution to the system of equations using substitution is given by:
x = 4 and y = 2.

Answer:
we have x = -62 or x = 66
Step-by-step explanation:
16=(x-2)^2/3
I would take square root first
4 = (x - 2)^ (1/3)
or -4 = (x - 2)^(1/3)
.....
4^3 = x - 2
64 = x - 2
x = 66
or -4 ^3 = x - 2
-64 = x - 2
x = -62
we have x = -62 or x = 66
7/19, 9/19 11/19
I hope this really helps
basically just add 2 on to the numerator
Answer:
64,512
Step-by-step explanation:
First, I multiplied 96 and 14, and I got 1,344.
Then, I multiplied 1,344 and 48, I got 64,512.
Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
